Dear Students,

M. Wong

Today I give you three doze passages to work on. They vary in length and difficulty. The first two passages are set in the form which you will encounter in paper III, but the last passage is presented in the form of MCQs. All the three exercises are designed to test your command of language items and usages.

Passage 1

For each blank space, think of ONE world which makes best sense in the passage. Write your answers in the appropriate spaces-provided.
